OTTO P. BINDELI-IARDT, OF LONDON, ONTARIO, CANADA.

APPARATUS FOR CARBONATING BEER, ALE, AND THE LIKE.

Specification of Letters Patent.

Patented Feb. 13, 1911?.

Application filed October 15, 1913. Serial No. 795,255.

To all whom it may concern:

Be it known that I, OTTO P. RINDELHARDT, a citizen of the United States, and resident of the city of London, in the county of Middlesex and Province of Ontario, Dominion of Canada, have invented a new and useful Apparatus for Carbonating Beer, Ale, and the like; and I hereby declare that the following is a full, clear, and exact description of the same.

The object of my present invention is to utilize the carbonic acid gas generated in the fermenting tun or tuns for recharging the finished liquid in the storage cask or casks by taking the carbonic acid gas as it is generated, discharging it direct into the finished liquid, and utilizing the pressure of the carbonic acid gas in the fermenting tun to force it through the said liquid, suitable means being provided for distributing the volume of carbonic acid gas into minute sprays, as it passes into the liquid.

In carrying out my invention the carbonic acid gas is conveyed direct from the fermenting liquid in the fermenting tun to the finished liquid in the storage cask, the pressure of the carbonic acid gas during the fermentation being utilized for forcing it from its place of origin to its place of use, the storage cask containing the finished liquid being provided with means for dividing the carbonic acid gas into minute sprays to facilitate its impregnation of the liquid as hereinafter set forth and particularly pointed out in the claim.

In the drawings Figure 1, is a broken elevation of the apparatus showing the manner in which the carbonic acid gas is conveyed from the fermenting tun or tuns to the finished liquid in the storage cask or casks.

Fig. 2, is an enlarged detail view of one of the distributors of the carbonic acid gas.

Like characters of reference refer to like parts throughout the specification and drawings.

The fermentation of the worts takes place in a closed fermenting tun a and the carbonic acid gas as ,it is liberated during the fermentation rises to the top of the worts and accumulates below its cover I).

As shown in Fig. 1 of the drawings the cover 6 is provided with an outlet pipe 0 fitted with a safety valve d and with a valve controlled pipe e leading to the closed storage cask f. As shown in Fig. 1 of the drawings the pipe 6 leads into the bottom of the storage cask f and, within it, is provided with a distributer g. This distributer consists of a metallic ring It, having a hollow pipe connection 2' coupled to the adjacent end of the pipe e,-and formed preferably with two or more passages or bores j leading from the hollow pipe connection, through which the carbonic acid gas can flow to the interior of the metallic ring 71,. Bolted to. each side of the metallic ring it are clamping rings 70, 7c, and between the clamping rings k, 70 and the metallic ring h are permeable covers Z, Z, said permeable covers being securely fastened to the metallic ring it by the clamping rings and forming with the metallic ring a distributing chamber m into which the carbonic acid gas is discharged through the passages j from the pipe 0.

The pressure of the carbonic acid gas in the fermenting tun forces it through the outlet pipe c, the pipe 6, the pipe connection 2', and passages -7, into the distributing chamber m, and from the distributing chamber m through the pores of the permeable covers Z, Z into the liquid contained within the storage cask fto carbonate it.

The fermenting tun may be connected with any desired number of storage casks, and the carbonic acid gas as it is liberated may be conveyed simultaneously to all the storage casks by a suitable pipe line r, the number of casks depending upon the capacity of the fermenting tun; any desired number of fermenting tuns may be coupled together and connected to the pipe line r,- and the storage casks may be provided with outlets 0, preferably connected together by a dischage pipe 3) having a gage q indicating the pressure in the discharge pipe.

The terms fermenting tun and storage casks have been used throughout the foregoing description and these terms are intended to include within their meaning, any vessels suitable for use in connection with the brewing or storing of the liquid which will permit of the carbonic acid gas being collected from the fermenting liquid and forced through the finished liquid to carbonate it.

Having now particularly described the nature of my said invention and in what manner the same is to be performed, I cleclare that what I claim is In an apparatus for carbonating beer, ale,

and the like, a distributor comprising an ana distributing chamber into which the car- 10 nular ring, a hollow pipe connection therebonio acid gas is discharged through said for, said ring having passages leading from passages from the bore of the hollow pipethe bore of the hollow pipe connection to the connection.
